I think that I have been able to determine wich one of my females laid the two strange eggs. It seems to be the smaller female of the two I have from Thomas Steffen. She shedded about 10 days prior to the time I found the eggs in the box. The other larger female kept in the same tank at this time is going into shed now. She is really plump compared to the other one.

My other three females don't seem gravid. I guess i have to put them into a semibrumation period and try again.

I still haven't been able to find my the cord to connect the camera to the PC, so pics can't be shown just yet.
